Hmm, error -5 is EIO, which in the channel switch code is used to
represent "PLL charge pump out of range". This is specifically the
error I was trying to fix... could you try without the 2 extra
patches? Maybe I did something wrong. (Without the 2 patches, channels
1..6 and 9..11 (12...14 not tested) throw this error, but channels 7
and 8 work.)

Also try extracting firmware from
ftp://downloads.netgear.com/files/GPL/WNDR3300-V1.0.29_gpl_src.zip's
wl_apsta.o file (newer than the one on mirror.openwrt.org - you may
need to add the extraction defines to fwcutter first; there is a
script in the fwcutter git tree, probably also in tarballs, that
generates extraction lists.) This is the firmware the specs are
written for; it's possible that the current firmware is simply not
good for LP-PHY (or maybe it needs code based on older specs).

When testing mac80211 drivers, always use "iw dev wlan0 scan", not
"iwlist wlan0 scan". (Though this shouldn't affect your results in
this case.)

Try bringing up the interface in monitor mode.
Also, try changing get_default_chan to return 7 instead of 1.
